It’s soft and the sides are that, but I needed a mattress that was like that for my husband to manoeuvre to get out of bed. I put a 4in topper on the top and are very happy with it.
Jane Taylor –
Reasonably comfortable. Inexpensive. Bought for occasional use and fine for that.

Iv had this matress for about 9 months at first it was comfy now its basically just springs digging into my ribs and everywhere else it’s okay for the price but it wont last long
Mrs F, SYorks –
Very comfortable, good quality and value. However, I picked this one because I didn’t want a soft mattress, so I picked ‘medium’ and it turned out to be ‘medium-soft’.

I have never been tempted to leave a review before – despite using Amazon a great deal. I’ve made an exception here to give a little back; I use customer feedback every time I shop with Amazon. This mattress arrived promptly enough but I was surprised to see it packaged rolled up like you would expect a foam mattress to arrive. Once unrolled, the quality of this mattress was immediately evident. It was poorly upholstered, sparsely sprung and very thin. I paid £195.00 for this and consider it worth no more than £20 – £30. It cost me nearly £15 to return the item (I rolled it back up to ensure the carrier would take it) and after initially denying that I had returned it, ‘the sleep people’ refunded me – but only after I could provide the date and time that it was signed for. I went on to buy a small mattress from Mattress Man. It cost a tenner less and is fantastic quality in comparison.
Review mad –
Delivered next day (originally advised 2 days). Came in a small box (for a mattress!) and the product expanded to full size very quickly. I purchased this for our 2 year olds first full sized bed but have tested it myself and it’s very comfy. For the money paid I simply cannot believe how good it is. I was quoted 3 times the price in a major high street store- they must have been in dream(s)land.
If anything changes as to the quality etc I’ll update this review as I’ve not had the opportunity to test the long term durability of the product.
Mr T –
This product arrived rolled up in a rectangular box. At first glance I thought we may have accidentally purchased a mattress topper instead of a mattress. However, once un-boxed and removed from plastic packaging the mattress opened out and took its proper shape….I was most impressed. The mattress is quite deep which helps from a comfort perspective. More importantly our 3 year old daughter is now sleeping through the night – bonus! This mattress can easily accommodate children beyond this age and a small adult.

Wow. Really impressed. This item was delivered 4 days earlier than expected and in a nice neat and easy to store box. I was a little apprehensive about how good the product would be as the box was compact and when I opened the box and took the rolled mattress out I was not hopeful. I must say I was pleasantly surprised when I cut the plastic bag that it was rolled in. The mattress is amazing, when it was vacuum packed I did not think it would be as deep or as bouncy as it is. It is one of the moist comfortable mattresses that I have ever laid on. My daughter has slept soundly and loves it, to the point she has told her grandparents all about it. Lol. To say I am pleased with the service and the product is an understatement and would definitely recommend this seller to friends and family. Thanks.
